Aggregate Industries’ revolutionary LytaScreed has been used as part of renovation works at one of the UK’s most prestigious educational institutions, University College London.

As part of UCL’s £1.2 billion refurbishment programme, main contractor Balfour Beatty was tasked with building a terrace next to the 19th Century Grade 1 listed Wilkins Building, providing a vital passage through the university’s Bloomsbury Campus while also serving as an outdoor events space.

In keeping with the architectural heritage of the Wilkins Building, the terrace included a Portland stone floor, with a new external staircase leading to the refectory at lower ground floor level. As such, the project required a lightweight podium screed suitable to carry natural stone paviours that could also provide a superior drainage system. Cue Aggregate Industries and its pioneering LytaScreed – one of the fastest drying and most versatile floor screed ranges available to the UK market.

Specifically designed and manufactured to meet the complex requirements of modern construction practice, when building the Wilkins Terrace 120 tonnes of LytaScreed Topped solution was utilised by placing the LytaScreed Base with a permeable 15mm sand cement topping.

LytaScreed was instrumental in helping the UCL revamp achieving ‘very good’ status BREEAM ratings. This is because not only does the innovative product reduce the weight of a screed by up to 50%, but being a secondary aggregate, it also cuts the demand for natural quarried material.

Steve Curley, Lytag general manager at Aggregate Industries, said: “The Aggregate Industries’ ground-breaking LytaScreed product proved the perfect solution for providing the lightweight podium screed suitable to carry natural stone paviours that the UCL refurbishment required whilst also creating an unrivalled drainage system.”
